The validation system described herein is expressly used with both static images as well as video.

FIG. 1 An image validation system 100 may comprise an electronic display 102 that is in electrical connection with a TCON 104. The TCON 104 may be in electrical connection with a screen capture device 108. The screen capture device 108 may be comprised of a Field-Programmable Gate Array (FPGA), though such is not required. The screen capture device 108 may be in electrical connection with a video player 106 and a processor 110. In this embodiment, the screen capture device 108 is positioned downstream of the video player 106 and upstream of the TCON 104. The processor 110 may be any type of processor, such as but not limited to, one having 300 MHz and 64 MB RAM capabilities. The processor 110 may direct the video player 106 to play an image or video (herein referred to simply as ‘image’). The processor 110 may determine which image to be played based on pre-programmed instructions. The instructions may also include, for example without limitation, the duration, order, frequency, timing, and the like of play for the images. The instructions may also include settings for the electronic display 102 while select images are being displayed including, for example without limitation, brightness, color, warmth, contrast, and the like. The instructions may be changed at any time. In exemplary embodiments, the instructions may be given by a separate processor.

The processor 110 may monitor the image that is currently being displayed and may check to see if the client who submitted the image requested an image validation. If the client did not request an image validation, the image validation system 100 may continue to operate normally. If the client did request an image validation, the processor 110 may direct the screen capture device 108 to take a screen capture of the displayed image. If the image is a video, the screen capture device 108 may take a static image screen shot of the video or may store a clip of the displayed advertising video. If the image is a static image, the screen capture device 108 may take a screen shot of the displayed image. The screen capture may be stored in an electronic storage device 112 that is electrically connected to the processor 110 and located locally to the electronic display 102 or transmitted through a network connection device 114 to a networked database 120 which may be located remotely.

In exemplary embodiments, a screen capture may be taken of every displayed image and the processor 110 may determine whether to keep or discard the screen capture based on whether or not the client has requested an image validation. In other exemplary embodiments, a screen capture may be taken periodically, for example without limitation, every 5 seconds. The screen capture device 108 may include a checksum or other confirmation data in the header or other portion of the screen capture file. In this way, if the same image is currently being displayed as was previously captured, the processor 110 may direct the screen capture to not be stored. In still other exemplary embodiments, a screen capture may be taken of every displayed image and stored for a period of time before being automatically deleted.

The screen capture device 108 may include a time and date stamp associated with the screen capture. The instructions to take and store the screen captures may be given by the processor 110 or may be given by a remote processor or application, such as but not limited to, an application installed on the networked database 120.

The network connection device 114 may be in communication with a communications network 118 such as, but not limited to, an intranet, internet, cellular network, the world wide web, or the like whereby the screen captures may be periodically transmitted to the client. The transmission may be by email, picture message, upload, or the like. In other exemplary embodiments, the screen capture data stored on the electronic storage device 112 or the networked database 120 may be made available to the client by way of a user interface 300 as illustrated and discussed with regards to FIG. 3.

In exemplary embodiments, the screen capture may be compressed and/or reformatted by the screen capture device 108 prior to being stored and/or transmitted on the communications network 118. This may limit memory and network usage. In exemplary embodiments, the compression may be at a 600:1 ratio. For example, but not to serve as a limitation, the native input format may be 3840×2160 RGB888 BMP format and the captured image may be compressed to 240×135 resolution and reformatted to a RGB565 PNG format. In other exemplary embodiments, the native input format may be 1920×1080 RGB888 BMP format and the captured image may be compressed to 240×135 resolution and reformatted to RGB565 PNG format. It is notable that these are merely exemplary, any size and format native input, any compression ratio, and any output sizes and formats are contemplated.

FIG. 2 In another exemplary embodiment, the image validation system 200 may instead comprise a video player 107 having two video outputs. A first video output which is in electrical connection with the TCON 104 and a second video output which is in electrical connection with the screen capture device 108. In this embodiment, the output of the video player 106, namely the advertising images, may be transmitted to both the TCON 104 and the screen capture device 108. The screen capture may be stored in an electronic storage device 112 that is electrically connected to the processor 110 or transmitted through a network connection device 114 to a networked database 120 which may be located remotely. The electronic storage device 112 or the networked database 120 may make the screen capture data available to the client by way of the user interface 300, as illustrated and discussed with regards to FIG. 3.

FIG. 3 In exemplary embodiments, the user interface 300 is a website. In other exemplary embodiments the user interface 300 is an Application Program Interface (API) configured to be utilized with another website or program. In still other exemplary embodiments, the user interface 300 may be a Graphical User Interface (GUI). Regardless, the user interface 300 may be in communication with electronic storage device 112 or the networked database 120 and may be configured to make the stored screen capture data available for viewing.

The user interface 300 may comprise a link 312 for viewing the screen capture data. Options to view the display status 302, network settings 304, system settings 306, sensor charts 308, unit upgrades 310, and the like may be made available after selecting the link 312 or accessing the user interface 300. The display status 302 option may provide a refresh feature 314 wherein a new screen capture may be taken. Information about the screen capture may be displayed including the time and date information and a preview of the screen capture. The full screen capture data file may be made available for download or viewing. Additionally, all of the stored screen captures may be available.

The network settings 304 option may permit the user to adjust settings and options related to the communications network 118, the network connection device 114, and or the networked database 120. The system settings 306 option may permit the user to adjust setting and options related to the processor 110 such as, but not limited to, what images are displayed, the duration, order, and timing of the images, when screen captures should be taken, time and date stamping, and the like. The system setting 306 option may also permit the user to adjust the settings and options related to the electronic display 102 such as, but not limited to, the brightness, contrast, color, and the like. The sensor charts 308 option may allow the user to view when the screen captures were taken and view the screen captures stored on the electronic storage device 112 or the networked database 118. The unit upgrades 310 option may provide the user with additional information regarding options, upgrades, add-ons, and the like for the image validation system 100.

In exemplary embodiments, the user interface 300 may be in communication with several image validation systems 100 or 200 so as to provide image validation for a plurality of image validation systems 100 or 200 simultaneously. The user interface 300 may display the status and other information regarding each of the image validation systems 100 or 200. The user interface 300 may additionally display or provide a means for accessing the current or stored screen captures for each of the image validation systems 100 or 200.

A person having skill in the arts will recognize that the look and feel, layout, options, and the like of the user interface 300 are merely exemplary and are not intended to be limiting. Any look and feel, layout, options, and the like are contemplated.

FIG. 4 In an exemplary embodiment, the image validation system 100 or 200 may operate by first displaying an image on the electronic display 102. If the client has not requested an image validation, the image validation system 100 or 200 may continue normal operations. If the client has requested an image validation, the screen capture device 108 may take a screen capture and transmit the screen capture data to the client. Alternatively, the screen capture data can be stored for later access by the client online. In exemplary embodiments, the screen capture device 108 may time and date stamp the screen capture data. The image validation system 100 or 200 may then resume normal operations.

FIG. 5 In another exemplary embodiment, the screen capture device 108 may take a screen capture of every displayed advertising image. The system may store the screen capture data on the electronic storage device 112 or the networked database 120, and if the client requests an image verification, the stored screen capture data can either be transmitted to the client or the client may be provided with access to the stored screen capture data. Alternatively, the system may discard the screen capture data if the client has not requested an image validation. In still other exemplary embodiments, the screen capture device 108 may take a screen capture of every displayed advertising image and the screen capture may be stored for a period of time before being automatically deleted.
